RESILIENT SUPRT FR CUSHION SEATS.

n Application filed December 22, 1926. Serial No. 156,491.

rlllhis invention relates to resilient supports for cushion seats, andhas particular' refer ence to a resilient-support for cushioned vehicleseats, the same being in the nature of an improvement upon prior UnitedStates May 11, 1926.v

ln constructing supports of this Character' l especially for vehicleseats, it has been noted where the seat vis of a width to accomodatemore than one person, the employment of a singleL resiliently mountedframe is of a disadvantage in view of the fact that where one personsits ononexside of the seat or where persons of extremely differentweights sit up on opposite sides of the seat, the single supportingframe has a tendency to become canted rendering the seat uncomfortable,strain ing the structure, and generally detracting from the efficiencythereof.

ln order to overcome the above-recited objections and to materially addto the general eliiciency of the structure, the present invenf` tioncomprehends a resilient support for cushion seats which includes astationary frame and a plurality of independently movable resilientlymounted cushion supporting elements which serve to closely conform tolocalized weights imposed thereon, thereby rendering the seat more`comfortable to the users.

Other objects reside in the features of r simplicity, rigidity andstrength of construc- 0 tion and the economy with which the same may beproduced.

TWith the above recited and other objects in view, reference is had tothe following specification and accompanying drawings in which there isexhibited one example or embodiment of the invention which is'in no wayintended as a limitation upon the scope of the appended claims as it isto be clearly understood that variations and modifications whichproperly fall within the scope of said claims may be resorted. to whenfound keX- pe'dient.

ln the drawings- Figure. 1 is a plan view of the seat support;

Fig. 2 is a longitudinal sectional view therethrough taken approximatelyon the line indicated at v2--2 in Fig. 1;

Fig. 3 is a transverse sectional view taken Letters Patents Nos.1,021,949 and 1,584,517, granted, respectively, on May 28, 1912, and`AReferring to the 'drawings by charactersr of reference, the seatsupport includes substantially rectangular 'upper and lower frames 10and 11, whichare connected by vertical or upright corner andintermediate members 12 and 13. Adjacent' the upper front portion of theframework a transversef bearing rod 14 is mounted, to which is pivotedin longitudinally spaced relation, elements in the nature of flexibleresilient straps is a fragmentary sectional View` 15, which arepreferablyfconstructed of sheet metal bent at a point substantiallyvintermediate the ends to provide a knuckle or sleeve 1G embracing thebearingrod 14. The remaining portions or leaves are bolted', riveted, orotherwise secured together at 17, with the free rear terminals .18 and19 slightly offset to receive and clampy therebetween a` continuousflexible transverse strip 2O of leather or other suitable material whichallows for a limited relative independent vertical movement of the freerear ends of the elements 15. The extremities of the terminals 18 ofeach element 15, are turned up as at 21,

and areapertured to receive the lowerends or convolutions 22 of coiledcontractile n springs 23, theupper ends or convolutions 24 of which aresuitably anchored to the upper frame member 10, whereby the rear freeends of the elements 15 are normally supported by the springs 28 andtensioned against downward movement. The elements 15 are normallydisposed ata rearward and downward inclination and are adapted toreceive thereupon a cushion seat A. In order to prevent rearwardgravitation ofthe seat A, the upper leaf of each element 15 adjacent itsrear end, is formed with an upwardly offset portion 25 which ispreferably formed integral therewith to provide an abutment or stopagainst which the rear end B kof the cushion seat abuts. The forward endC of the cushion seat A is adapted to directly rest upon the upper framemember 10, and a depending flap or apron D is carried by the forward endC to overlie and conceal the stationary frame of the support. In orderto space and prevent lateral shifting movement of the fulcruniiedforward ends of the elements or straps 15, the upper frame l() may havebolted or otherwise secured thereto spacing devices 2G which also serveto support the bearing rod '14.

In use, it is obvious that a wcightvimposed upon the cushion seat A willeffectdownward movement only of the number of elements or straps l5 overwhich the weight is imposed with .only a slight movement of the adjacentelements l5 on opposite sides by the fiexible connecting strip 20. Theelements l5 in addition to moving` rbodily down under the weigh-t andabsorbing the shoclrs and ars incident to travel over t-he road, arealso capable of` a slight flexing or bowing to augment the function ofthe springs 23.

/Vhat is claimed is:

l. A resilient support for cushion seats, including a 5stationary frame,a plurality of independently relatively movable cushionsupportingelements resiliently mounted in the frame at one of their ends, meansfor tensioning the same against downward movement at their opposite endsand for normally retaining said ends elevated, and a flexible connectionbetween the latter ends for limiting the relative movement between theelements. i

2. A resilient support for cushion seats, including a stationary frame,a plurality of resilient cushion-supporting elements, means forindependently fulcruming the forward arf/'01,2331

ends of the elements to the upward forward portion of the frame,contractile means of connection between the rear ends and the upper rearportion of the supporting frame for tensioning the same against downwardmovementA and normally retaining the same elevated, said elementsconsisting of a length of resilient material bent at a pointsubstantially intermediate the ends to provide a sleeve, the remainingportions constituting leaves, securing means attaching the leavestogether, and a flexible connecting means between the rear ends of theelements to permit of relative limited independent movement.

3. A resilient support for cushion seats, including a stationary frame7a plurality of resilient cushion-supportin'g elements, means forindependently fulcruming the forward ends of the elements to the upwardforward n portion of the frame, contractile means of connection betweenthe rear ends and the upper rear portion of the supporting frame fortensioning the same against downward movement and normally retaining thesame elevated, said elements consisting of a length of resilientmaterial bent at a point substantially intermediate the ends to providea sleeve7 the remaining portions constituting leaves, securing meansattaching the leaves together, and a i'iexible connecting means betweenthe rear ends ef the elements to permit of relative limited independentmovement, the rear ends of the leaves having clamping engagementtherewith.
